Aperson uses a shared needle to inject a drug and comes in contact with infected blood. which type of contact is this?

Direct contact

Explanation:

A direct contact happens when a healthy person gets infected with a disease via direct physical contact with body fluids (such as blood), in the case of an injection the infected person's blood gets in contact with the healthy person's blood through the needle, causing this last one to get infected.
